Entity AI Framework

-Removed single ai from test mob (the handle movements method)
-Added new list to entity of type EntityAI
-Added new EntityAI class thats abstract and takes 1 parameter of Entity
with 2 children (EntityAIAggroPlayer, EntityAIRandomWalking)
-To add a type of ai to a mob you simple add something like this ---
this.entityBehaviors.add(new EntityAIRandomWalking(this)); --- to the
init method
